The present specification relates to an ink composition including a first solvent represented by Chemical Formula 1 and a compound represented by Chemical Formula 2; an ink composition including a first solvent represented by Chemical Formula 1, a second solvent represented by Chemical Formula 3 or Chemical Formula 4, and a compound represented by Chemical Formula 2; an organic light emitting device including the ink composition and a cured material thereof; and a method for manufacturing the same.

Ink composition, organic light-emitting device using same, and manufacturing method therefor

The present invention relates to an ink composition for an organic light emitting device that can be applied to an inkjet process. The ink composition comprises a compound represented by the following Chemical Formula 1, a first solvent of aromatic esters having a boiling point of 260 to 400&#xb0; C., and a second solvent of aliphatic ethers or aliphatic esters having a boiling point of 200 to 400&#xb0; C., wherein the boiling point of the first solvent is higher than that of the second solvent. When this is applied to an inkjet process, it can form a flat film with a smooth surface when dried after forming the ink film. wherein L, Lto L, Ar, Ar, Rto R, Yto Y, and nto nare described herein.
